Levels of physical activity w/o becoming overly tired. ® eg: activities of daily living such as shopping, gardening, house keeping, child rearing, work-related activities, etc ® ACHIEVED BY THE REGULAR MOVEMENT OF MUSCLES THROUGH A VARIETY OF EXERCISES

Your Body is A Work of Art…. ® The Training Effect… ® “If you build it…they will come!”

Common Goals-What’s Yours ® Weight Loss ® “In-shape” ® Toned ® Ripped ® “Buff” ® Benchmarks ® Events

Basics of a Physical Activity Program Warm-Up ® A warm-up helps prevent injuries ® The warm-up increases the body's temperature and the heart rate. ® A warm-up should include some running-in-place or slow jogging, stretching, and slow exercises. ® It should last five to seven minutes Cool-Down ® One should cool down properly after exercising. ® Helps to gradually slow the heart rate. ® One should walk and stretch until their heart rates return to less than 100 BPM and heavy sweating stops. ® This usually happens five to seven minutes after the conditioning session.

Overload ® In order to produce increased results, you have to push your body out of its comfort level. ® By exercising at a level above normal, your increase the demand on your body and slowly get better. Progression ® The how hard and how long you work must increase in a slow and steady manner. ® Once the body has become used to a certain weight or intensity level, it is time to increase the demand or work to shock the muscles again.

Specificity ® Working on the part of the body you want to get better. ® This specificity is related to: ® Muscles ® Types ® By of Exercise singling out these parts of the body when exercising you work them harder than the rest of your body. Reversibility ® The “Use it or Lose it” principle. ® If you don’t use your muscles they will atrophy (shrink!)

Your Task. . . . . 6 Basic Principles of Training ® Definition or explanation of each Principle in your own words. ® Provide at least 1 examples of each Principle. ® Draw a picture to explain each. ® Be creative….

The FITT Formula: When planning for fitness, the FITT formula is a useful tool for determining how often, how hard, and how long you should be active. -Frequency of Activity -Intensity of Activity Time Spent in Activity -Type of Movement in Activity • F requency • I ntensity • T ime • T ype

FITT Factors Applied to Physical Conditioning CRE F I T T MS ME 3 - 5 times Weekly 70 -90% Max Heart Rate 20+ min.

Aerobic vs. Anaerobic ® Talk Test ® Aerobic: exercise that you can breath easily for a longer period of time. Examples: ® Anaerobic: exercise where you have to breath hard for short bursts of time. Example

Muscular Strength and Endurance ® Develop muscle by overloading ® Strength ® – Lots of weight, little times “LIFT MORE” ® Endurance l –Less weight, more times “LIFT LONGER”

Flexibility ® Ability to move your muscles and joints comfortably ® Point of mild discomfort ® Stretching makes your muscles more flexible. ® Prevents ® Ballistic against injury vs. Static?

Body Composition ® Amounts of fat to lean muscle mass ® Essential: 3 -7% (M), 13 -15% (F) ® Healthy: 12 -15% (M), 18 -21% (F) ® How to Measure? ® Obesity: ® Men: if greater than 25% ® Women if greater than 32%

Obesity Defined ® Obesity means that you have an unhealthy amount of body fat. ® Everyone needs some body fat, but too much fat increases your risk of developing lifestyle diseases. ® Defined by BMI Body Mass Index ® BMI is a way of estimating total body fat for most people.

Note: BMI chart is for adults ® 25 -29. 9, “Overweight" ® 30 or above “Obese"

BMI For Teens? ® ® ® Write down your weight in pounds. Divide your weight by your height in inches. Divide the answer from step 2 by your height in inches. Then multiply the answer from step 3 by 703. The resulting answer is your BMI.

There is no Magic Pill

ENERGY EQUATION (ENERGY BALANCE) ENERGY IN = ENERGY OUT = NO CHANGE ENERGY IN > ENERGY OUT = GAIN WEIGHT ENERGY IN < ENERGY OUT = LOSE WEIGHT

Energy Equation Components Energy In Energy Out

FACTORS INFLUENCING “ENERGY OUT” METABOLISM-Process and rate in which the body uses the energy from food (Calories). ® Basal Metabolism -absolute minimum amount of energy required. ® or Resting Metabolic Rate -The energy required to maintain vital body functions, including respiration, heart rate, body temp. , and blood pressure, while body is at rest. -(70%) ® Burning calories from eating>10% ® Burning calories from activity 10 -30% IT IS JUST AS DANGEROUS TO YOUR HEALTH TO BE UNDERFAT AS IT IS TO BE OVERFAT ®

What is easier or healthier? Eat less or Exercise more…

How to view the Question…. . Healthier Eat Less Exercise More Easier

Energy Expenditure - Examples Burning Calories with 30 minutes of walking/running at 3. 0 mph and 6. 0 mph Body weight 200 lbs 150 lbs 250 lbs This w i l l Calories burned 158/459 118/364 198/610 1 lb. of fat tissue stores 3, 500 calories or energy

Muscle is 70 X more metabolically active than Fat: What does this mean?

When weight maintenance moves to unhealthy choices…. . Behaviors Discussed: ®Eating Disorders ®Female Athlete Triad ®Compulsive Exercising

General Background ® Mental in nature but problems cause Physical Effects. ® Best characterized as ‘Addictions’ ® It’s not just about disordered eating…it’s about relationships w/ others and oneself…

At a certain point, an eating disorder ceases to be "about" any one thing. It stops being about your family or your culture. Very simply, it becomes an addiction. . . -Wasted, Marya Hornbacher (p. 64)

Basic Stats ® ~3% of women during lifetime. ® Estimated 5 million ® Girls more than guys (~9/10). ® High risk of other mental and physical illnesses that can lead to death. ® Since 87’, hospitalizations increased: ® ® 34% among women under 15 29% among 15 -24 year olds.

Eating Disorders Defined ® anorexia nervosa ® refuse to maintain a normal body weight ® fear of gaining weight (Starvation, <1600 cal/day) ® Not a normal view of the shape or size of their bodies. ® bulimia ® eating nervosa lots of calories followed unhealthy ways to burn calories ® Too much attention on body shape and weight.

Unhealthy ways to burn calories ® Drugs that make you use the washroom ® Forced throwing up ® Diet pills ® Serious over exercising

“It's disgusting but [my eating disorder] was my safeguard, my sure thing, my life for all those years. . . It was something I knew for sure, no question, I was good at. ” -Wasted, Marya Hornbacher (p. 121)

These evil thoughts, from where are they born? -Verde's Macbeth-

“In one national survey of over 6, 700 adolescents in grades 5 -12, half of girls and 1/5 of boys reported dieting to lose weight. ”

She was afraid to eat. She lost 25% of her body weight. She strove for perfection. Her desires and passions disappeared. She had angry outbursts. She stopped having her periods. She felt isolated. She was always cold. She desired control. She felt weak. She denied her hunger. Fine hairs grew on her entire body. She was depressed. She suffered from insomnia. She had a distorted body image. Her heartbeat was irregular. She craved attention. She almost died.

Energy Equation & Weight Maintenance ® Exercise is essential for weight management because it is a major part of the energy equation. ® Exercise increases the amount of energy the body expends, helping to manage both body weight and composition. ® Longer duration and more intense exercise burns more calories.

A combination of regular exercise and good nutrition is the best way to maintain a healthy lifestyle.

Physical Fitness 101 ® Any exercise you take part in is going to be good for your body/mind. ® The more MUSCLES & JOINTS you incorporate the better. ® The important concept is to add VARIETY into your exercise routine. . ® Cross-Training

Words of Wisdom ® “Exercise shouldn’t be a CHORE!” ® “It doesn’t matter what you do…. as long as you DO SOMETHING!” ® “If something is important to you, you will MAKE TIME FOR IT!”
